I have songs made in audacity that are just bass and guitar. I need to load them into reason so i can add drums. is there any way to do this? when I try to load my wave files into a sampler on reason, it doesn't seem to work. Also I want to repeat a certain drum pattern for a few mesures and then repeat another drum pattern with a faster tempo afterwards. is there any way to do this or does reason only allow you to create beats with redrum that are all the same tempo for a song?
